Hello Esteemed Excel Community...

I thought I knew all about the VLOOKUP function, but...

Here's my deal...on one worksheet called SOURCE, I have two columns of data,
named UserID and Name.

On another worksheet in the same file, named HOURS, I have 5 columns named
UserID1, UserID2, UserID3, Name, and Production Hours. The reason for the
three UserID* columns is because we are still using a BTrieve system and some
users have up to three UserIDs to identify the same name.

So, what I am trying to do is to capture the Production Hours data for a
given employee based on the single UserID in the SOURCE worksheet, and
compare this value to the three UserID cells on the HOURS worksheet fore a
match, and then copy Production Hours value. The names should match with a
given UserID with slight differences.

So, I know a =VLOOKUP formulasay in cell b3 on the SOURCE worksheet, would
work in the form =VLOOKUP(b1,HOURS!b1:b5,FALSE) would yield the proper value
if I was just concerned with comparing one unique UserID to another unique
UserID, but how do I accomplish this with testing which one of the UserID
values matches, and then fetching the value if there is a match? Can this be
done with the VLOOKUP function?

Thank you in advance.

Mark :)
